Subject: [PATCH 02/15] mm/hmm: fix header file if/else/endif maze v2
Date: Thu, 22 Mar 2018 20:55:14 -0400 [thread overview]
Message-ID: <20180323005527.758-3-jglisse@redhat.com> (raw)
In-Reply-To: <20180323005527.758-1-jglisse@redhat.com>
From: Jérôme Glisse <jglisse@redhat.com>
The #if/#else/#endif for IS_ENABLED(CONFIG_HMM) were wrong. Because
of this after multiple include there was multiple definition of both
hmm_mm_init() and hmm_mm_destroy() leading to build failure if HMM
was enabled (CONFIG_HMM set).
Changed since v1:
- Fix the maze when CONFIG_HMM is disabled not just when it is
disabled. This fix bot build failure.
- Improved commit message.
